Abstract

Raw mill is one of the main parts of the cement-making process where there is a process of grinding limestone, silica rock, clay, and iron ore into the raw mix. This grinding process is carried out by a roller tyre which is rotated by a table due to the hydraulic force from the motor being driven electric current. The raw mill has four main functions, namely milling, drying, which is assisted by a pre-heater and hot temperatures from the kiln, separation, and transportion. The process of grinding limestone and other materials into the desired micron size is carried out by four roller tyres, at the same time there is wear occured on the four roller tyres caused by people, materials, methods, and the machine itself. The research aims is to determine the wear characteristics of roller tyres in raw mill. Non-experimental research approach was used and a descriptive methods was used in which is to observe, analyze, describe, to obtain information. From the results of the research conducted, it was found that at the measurement point of 0 mm - 700 mm, the highest roller tyre wear occurred at the point was 500 mm with a wear depth of 17 mm. Based on the calculation of the four roller tyres running hours, the results are that the roller tyre 2 has the shortest running hours among the other four roller tyres with an average running hour of 585.21 hours, and the roller tyre 4 has the highest running hours with an average running hours of 1874.55 hours. Based on research conducted, the highest wear on the four roller tyres was occured on roller tyre 2 with an average wear of 70,329.7 mm³/hour and the roller tyre with the lowest wear was roller tyre 4 with an average wear of 13,369.4 mm³/hour. To investigate wear on the four roller tyres was uniform or not, Kruskal-Wallis test was conducted. The significance value of the Kruskal-Wallis test was 0.076, which means that there was not significant difference in the wear on the four roller tyres. Keywords: Roller tyre, Running hours, Measuring point, wear, Kruskal-wallis test, raw mill.
